More particularly, the present invention relates to an outer wall construction apparatus for constructing outer wall of a building of which the slab between floors or wall surface is completed with plate structures, which not only enables enhancing reliability for working and shortening construction period but also makes construction of outer wall for a curved surface which has been considered as a complicated work possible.

BACKGROUND ART

Generally, an outer wall refers the outer wall shown outside of a building, and it has been embellished mainly by paints or bricks in the past. However, recently, methods of fixing stone or metal plate structures to outside wall surface of a building is being used a lot in pursuing stylish appearance. At this point, the stone or metal plate structures fixed to outside wall surface of a building is differently called exterior panel.

While, the methods of fixing the plate structures to a completed wall surface of a building are classified into wet wall support system and dry wall support system, the wet wall support system is a method that arranges the plate structures on the outside wall surface of a building face-to-face and place cement between them and fix each other, and is rarely being used since construction period including curing is long and its workability and constructability are low. In the mean time, the dry wall support system is a method that fixes plate structures to outside wall surface of a building using separate fixation tools made up of such as metal, and its workability and constructability are relatively high.

However, the stone or metal plate structures are delicate to handle because of their heavy load, and accompany a long period of time for working in the high altitude in case of a multistory building since it is required to work at the outside of a building of which the wall surface is completed. In addition, the fixation tools for fixing the plate structures to wall surface of a building has a simple structure that is fixed to anchor bolts of the wall surface in advance and afterwards plate structures are fixed to with bolts and nuts. While, the work thereof is delicate since fixation work of the bolts and nuts is done in the narrow space between wall surface and plate structures, and partial repair and replacement thereof are impossible once construction thereof is completed unless entire outer wall is dissembled.

Therefore, the conventional outer wall construction and repair require a lot of labor, and has problem in that there are many dangerous elements such as high altitude work that risk the safety of workers.

MODE FOR INVENTION

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a procedural perspective view that shows a figure of constructing outer wall of a building using an outer wall construction apparatus in accordance with the present invention.

Before full description, as shown in the drawing, the objective building of which the outer wall is constructed through an outer wall construction apparatus in accordance with the present invention can be in shape that floor and slab 2 of ceilings for each floor and pillar 6 except outer wall are provided, and the slab 2 and pillar 6 can be steel frame using H beam or concrete structure, etc.

And an outer wall construction apparatus in accordance with the present invention for constructing outer wall for such a building with plate structure such as stone has basic structure that includes first bracket 10 fixed to the side of slab 2 of each floor, a plurality of fixation beams 20 fixed to the first bracket and substantially projected vertically from the side of corresponding slab 2, a plurality of horizontal beams 30 fixed to fixation beams 20 and arranged horizontally, and a plurality of vertical beams 40 fixed to outside of horizontal beams 30 and arranged vertically, while stone or metal plate structures 100 of which the four sides are continuously supported by second bracket 50 constitute an outer wall along outside of the respective vertical beams 40.

At this point, first bracket 10 can be fixed with pre-inserted anchor bolt along the side of slab 2, first bracket 10 and fixation beam 20 can be fixed to each other by welding or with fixation material such as bolt and nut, fixation beam 20 and horizontal beam 30 or horizontal beam 30 and vertical beam 40 respectively can be fixed to each other by means of welding.

Accompanying FIG. 2 and FIG. 3 are respectively an exploded perspective view for essential part and a side view of an outer wall construction apparatus according to the present invention, also referring to FIG. 1, hereinafter, an outer wall construction apparatus according to the present invention will be described in detail in accordance with the outer wall construction process using it. Also as for more details, reference will also be made to adequate drawings separately referred.

As shown, in order to construct a outer wall using an outer wall construction apparatus according to the present invention, firstly, a plurality of first brackets 10 are made fixed using anchor bolt 4 pre-inserted along the side of slab 2 of each floor.

At this point, first brackets 10 have no limitation in shape as long as they can support fixation beams 20 mentioned afterward securely, however, it is preferable to be arranged at a regular interval if possible, and fixed securely by using fixation material 12 such as anchor bolt 4 at the side of slab 2 and nut inserted hereinto or by welding as shown in the drawings. And such a work can be done on the slab 2 of each floor.

Subsequently, fixation beams 20 are made fixed to be substantially projected vertically from the side of corresponding slab 2.

At this point, a steel tube of which the shape of cross section perpendicular to its longitudinal direction is square in figure is used for fixation beams 20, the degrees of projection in which fixation beams 20 are projected from the side of corresponding slab 2 of each floor is not required to be same, however, it is preferable to adjust their length for each end of them to be on the same perpendicular surface. And welding or fixation material such as bolt and nut can be used as shown in the drawings for fixation of first bracket 10 and fixation beam 20.

Subsequently, horizontal beam 30 is made fixed to at least one that forms the same horizontal row among a plurality of fixation beams 20 and horizontally arranged.

At this point, a steel tube of which the shape of cross section perpendicular to its longitudinal direction is square in figure is also used for horizontal beams 30, after holding on the upper surface of at least one fixation beam 20, which are welded to be fixed securely.

Subsequently, a plurality of vertical beams 40 are made fixed to outside of horizontal beams 30 to be arranged vertically.

At this point, respective vertical beams 40 are fixed securely to horizontal beams 30 in a way means such as welding. Lower ends of the vertical beams 40 can be buried into the ground if necessary. Respective vertical beams 40 are characterized in that an opening part 44 has the shape of slit along the longitudinal direction of the outer surface of a square steel tube that has a hollow 42 penetrated in the longitudinal direction.

More specifically, accompanying FIG. 4 is a cross sectional view that shows a cross section of vertical beam 40 perpendicular to the longitudinal direction. The cross section of vertical beam 40 is in shape of square that is penetrated by hollow 42, of which the respective edges are rounded, an opening part 44 in the shape of slit is formed along the longitudinal direction of outer surface corresponding to the side opposite to horizontal beam 40. Here, ends of each rib 46 of both sides that forms opening part 40 of vertical beam 40 are curved to have inclination into inside of vertical beam 40 in other words into inside of hollow 40. For example, width (e) of opening part 44 can be about 10˜15 mm, degree of curve of both side ribs 46 respectively 2˜4 mm, preferably about 3 mm, where width (c) and thickness (b) of vertical beam 40 are about 75 mm and 45 mm respectively.

And such a vertical beam 40 maintains first and second spaces with vertical beams 40 adjacent thereto to the left and right(provided that a>b, hereinafter referring to a, b in FIG. 1). At this point, as long as the first and second spaces (a, b) maintains the relation of a>b, they can be adjusted appropriately in accordance with the size of plate structure 100. For example, in case that width of plate structure 100 is about 780 mm, first space a can be about 540 mm, second space b can be about 240 mm.

Now coming back to FIG. 1 through FIG. 3, subsequently, at least one second bracket 50 is made fixed to the outer surface of each vertical beam 40.

At this point, second bracket 50 is so called L type bracket showing elbow shape, and includes fixation end 52 fixed tightly to outer surface of vertical beam 40 and support end 56 that is vented perpendicularly thereto and projected horizontally from outer surface of vertical beam 40. First bolt hole in shape of long aperture of which the up-down direction, that is, Y axis direction in the drawing is longer is made penetrate fixation end 52, and second bolt hole in shape of long aperture of which the front-back direction, that is, X axis direction in the drawing is longer is made penetrate support end 56. In addition, in order to fix second bracket 50 to vertical beam 40, first bolt 60 and first nut 70 according to the present invention are used. Accompanying FIG. 5 is a partial exploded perspective view of FIG. 2 for explaining a method for fixing second bracket 50, and FIG. 6 is a plan view of a bolt 60.

Firstly, head 62 of first bolt 60 shows shape of rectangle or that similar thereto that has short side narrower than the width of opening part 44 of vertical beam 40 and long side wider than the width of opening part 44 of vertical beam 40 but narrower than the width of inner part of vertical beam 40. And therefore, after inserting into hollow 42 through opening part 44 while head 62 of bolt 60 is stood upright, head 62 of bolt 60 will be entangled in both side ribs 46 when rotated about 90 degree, in such condition, at least one second bracket 50 can be fixed securely to vertical beam 40 respectively by method that makes screw axis 65 that is projected outward through opening part 44 of vertical beam 40 pass through first bolt hole 54 and makes first nut 70 coupled therewith.

At this point, as described above, since both side ribs 46 of vertical beam 40 are curved to have inclination into inside of hollow 42, by which elastic force is produced when first bolt 60 and first nut 70 are being coupled, more secure fixation is possible, and it is possible to conveniently fix a plurality of second brackets 50 to one vertical beam 40 in accordance with worker's intention.

Particularly, referring to FIG. 6 that is a plan view of first bolt 60, middle part of inside surface of head 62 of first bolt 60 toward screw axis 65 can form stepping part 64 that is projected to have stepped difference toward screw axis 65, the height (h) of the stepping part 64 is smaller than the thickness of rib 46 (referring to FIG. 4 g) and the width (i) of stepping part 64 in the direction of long side of head 62 is smaller than the width of opening part 44 of vertical beam 40 (referring to FIG. 4 e). Accordingly, after standing upright and inserting head 62 of first bolt 60 into opening part 44 of vertical beam 40, if it is rotated about 90 degree, rest parts of head 62 except for stepping part 64 will be entangled in both side ribs 46, and stepping part 64 will be placed between both side ribs 46. The reason why head 62 of first bolt 60 has such configuration is to seek more convenient work and more secure fixation by preventing rotation or falling out in the left and right of first bolt 60 when joining vertical beam 40 and second bracket 50 together.

Describing in succession, flange 72 is formed around along one end of first nut 70 contacting fixation end 52 of second bracket 50 and expands substantial area. Jagged protrusions 74 in the shape of barbs are formed along such a contacting surface of flange 72 in the reverse direction of coupling of first nut 70. Consequently, after coupling first nut 70, since jagged protrusions 74 are producing strong frictional force for first nut 70 not to be loosened, more secure joining of vertical beam 40 and second bracket 50 becomes possible.

Accompanying FIG. 7 and FIG. 8 show modified embodiments of vertical beam 40 and first bolt 60 respectively as a practical application of technical idea of the present invention, FIG. 7 corresponds to aforementioned FIG. 5, and FIG. 8 corresponds to aforementioned FIG. 7. Therefore, in order to avoid repeated explanation, same reference numerals of the drawings and same terms will be used for the same parts that functions the same, while, reference additional numerals will be given for describing characterizing parts.

Firstly, vertical beam 40′ according to a modified embodiment of the present invention comprises guide ends 48 that is formed by venting vertically and prolonging end parts of both side ribs 46 forming opening part 40′ into inside hollow 42. And at first bolt 60′ according to a modified embodiment of the present invention, a couple of guide grooves 66 are formed outsides of both sides of stepping part 64 on inside surface of head 62 toward screw axis 65 for guide ends 48 of vertical beam 40 to be freely inserted hereinto. Here, the depth (k) of the couple of guide grooves 66 is bigger than the length (j) of guide ends, and through those guide ends 48 and guide grooves 66, it is possible to further more surely prevent rotation or falling out in the left and right of first bolt 60′ according to a modified embodiment of the present invention, which ensures more convenient work and more secure fixation.

Coming back to FIG. 1 through FIG. 3, subsequently, stiffener plate 80 that substantially prolonging support end 56 of second bracket 50 is made fixed to support end 56 of second bracket 50.

Here, stiffener plate 80 shows the shape of metal plate which third bolt hole 82 penetrates, of which the thickness is same as support end 56 of second bracket 50. Accordingly after laying stiffener plate 80 over support end 56 of second bracket 50, it is possible to securely join support end 56 of second bracket 50 and stiffener plate 80 using second bolt 92 penetrating both second hole 58 and third bolt hole 82 and second nut 94 coupled therewith, and stiffener plate 80 as such substantially prolongs support end 56 of second bracket 50 and supports following plate structure 100.

Subsequently, an outer wall is made realized by holding plate structure 100 and arranging to be continuous in four directions for at least four parts of upper and lower sides to be supported by support end 56 of second bracket 50 or stiffener plate 80.

At this point, plate structure 100 can be not only in shape of a rectangle that can be arranged to be continuous in four directions but also in various shapes such as a triangle, a pentagon, a hexagon, etc.

Meanwhile, if necessary in the process mentioned above, additional pin 96 that penetrates support end 56 of second bracket 50 or stiffener plate 80 and penetrates to be inserted into upper and lower surfaces of two plate structures 100 neighboring each other upward and downward, for which pin hole 84 is formed on support end or stiffener plate 80, and therefore plate structure can be fixed sill more securely.

After this, finally, when an outer wall by plate structures 100 is completed, adhesive waterproofing material such as cement or silicon is inserted into in between and finished, hereby outer wall construction using an outer wall construction apparatus according to present invention become all completed.

Meanwhile, in above-mentioned, an outer wall construction process for a building of which the slab of each floor is completed without additional outer wall surface was described for convenience, however the present invention is not limited thereto, and of course, an outer wall construction apparatus according to the present invention can be applied for outer wall construction for a building with wall surface. That is, in case of a building of which wall surface is completed, after fixing first bracket 10 using anchor bolt 4 inserted into the wall surfaces, a plurality of fixation beams 20 are fixed to be substantially vertically projected from the wall surface using the first bracket 10, and a plurality of horizontal beams 30 are fixed to the fixation beams 20 to be arranged horizontally, and then a plurality of vertical beams 40 arranged vertically on outward side of the horizontal beams 30 to complete basic structure, while outer wall can be completed by arranging plate structures 100 adjacent to each other to be continuous in four directions after fixing not only second bracket 50 but also stiffener plate 80 along outer surface of each vertical beam 40, which can be easily understood by those skilled in the art if referring to above description even though separate drawings are not presented.

In addition, in case of using an outer wall construction apparatus according to the present invention, it is possible to embody an curved wall surface which has been considered as a delicate work.

That is, accompanying FIG. 9 shows plan view for embodiment of curved outer wall using an outer wall construction apparatus according to the present invention. An outer wall can be constructed easily by above mentioned method if steel tube that is vented in shape of curved line is used.
